What Causes the Pop?

When you visit your San Jose chiropractor, and get a spinal manipulation or adjustment it is often accompanied by an audible crack. This noise is created when the joint is moved with a specific manual thrust at the end of the passive range of motion with in the joint. The commonly accepted cause of this pop is the cavitation of the spinal facet joints. This when there is a lower pressure in the joint causing gas bubble formation and a rise in pressure, cause by the manual thrust, implodes or pops these bubbles creating the cracking noise.
